Description
Technical field
The present invention relates to a kind of emulsion splitter compsn and application thereof that is used for lubricating oil.
Background technology
The emulsion splitter that in lubricating oil, uses also is non-emulsifying agent usually.It is many-sided causing lubricated oil content water-based difference or the emulsive reason takes place.The one, lubricating oil viscosity is high; The 2nd, in industrial lubricant, be added with various additives, wherein major part is the tensio-active agent that emulsification function is arranged; The 3rd, oil product is in use oxidized to have produced easy emulsive compound such as carboxylic acid, and the resistance to emulsion of oil is degenerated.Refining depth, the suitable various additives of selection of deepening base oil no doubt are a kind of problems that should at first consider, are the main paties that improves the lubricating oil resistance to emulsion but add emulsion splitter.
After adding emulsion splitter; Emulsion splitter is adsorbed on oil/hydrosphere facial mask, can change oil/water termination tension force, eliminates the obstacle (promptly eliminating the protective membrane of liquid pearl outside) that the disperse phase liquid pearl mutually combines; The liquid pearl is combined easily and realize changing mutually, thereby reach branch water purpose.A kind of emulsion splitter efficiently must possess stronger surfactivity, excellent wetting capacity ability and enough flocculation and binding abilities.
Owing to emulsion splitter all has certain scope of application, oil source in gene basis changes sometimes, production technique is adjusted, operational condition fluctuates and causes that the trace of oil base stock composition changes; Or because of the use of multiple additives has changed the surface property of oil product, so that cause the variation of oil product demulsification performance, and make a kind of emulsion splitter of independent employing, be difficult to make the demulsification performance of lubricating oil product to get a desired effect.In addition, in a kind of lubricating oil, add multiple emulsion splitter simultaneously, also can can't realize the effect that multiple emulsion splitter performance shows simultaneously owing to the variety of the composition and the additive thereof of lubricating oil.
So, how a kind of lubricant demulsifier compsn is proposed, make it have good demulsification, and have use range widely, then become the technical problem that industry is thirsted for solution for a long time always.
Summary of the invention
Main purpose of the present invention is, overcomes the defective of the emulsion splitter existence of existing one-component, and a kind of emulsion splitter compsn is provided, and technical problem to be solved is to make it improve demulsification, enlarges use range, thereby is suitable for practicality more.
Another object of the present invention is to, a kind of lubricating oil is provided, technical problem to be solved is to make it have good emulsion resistance effect.
The object of the invention and solve its technical problem and adopt following technical scheme to realize.According to a kind of emulsion splitter compsn that the present invention proposes, it is made up of Tritolyl Phosphate type emulsion splitter and polyether type demulsifying agent, and wherein the mass ratio of Tritolyl Phosphate type emulsion splitter and polyether type demulsifying agent is 4: 1-6.Described emulsion splitter preparation of compositions method is Tritolyl Phosphate type emulsion splitter and polyether type demulsifying agent to be measured to stir in proportion get final product.
The object of the invention and solve its technical problem and also can adopt following technical measures further to realize.
Preferable, aforesaid emulsion splitter compsn, wherein said Tritolyl Phosphate type emulsion splitter is Tritolyl Phosphate DM45 or similar structures material, its molecular structural formula is:
